Very good seat, very comfortable, good food, and good service.

It was a good flight, very comfortable seats for sleeping in business class. Probably the most comfortable business class seat I've ever had (20+ times in business class on various airlines). Service was good, but the only downside is my screen didn't work and it had to be reset multiple times to get it to shut off. I had to block my eyes because the screen was white almost the entire flight and I wore an eye mask when I slept. But when eating and reading in my seat, my eyes hurt because the only way to turn the screen off was reset it and the screen would only be off for a few minutes at a time.

All reviews good because...flight from BWI to London ,economy seats was miserable. I usually book 1,step up from economy but this would have added 1500 bucks 1 way. Bit the bullet and upgraded for retun flight, otherwise all ratings would have been rock bottom.

Great. It was awesome to have boarding from the front and back of the plane as it made the process go very quickly

It was okay. The airplane was a little smaller than a flight from Thailand to Helsinki.

Wish that everyone would board the back of the plane first. Also let kids on first. The gate wasn’t open at arrival and we waited 45 minutes to takeoff. They made up for time in the air.

This was an absolutely exceptional flight. The flight attendants were extremely attentive and very friendly. They seemed to go out of their way to make us comfortable and to make sure that we had everything we needed., We were in business and were very happy with the size and the details for our pods. We would definitely recommend Finnair and will definitely be flying with them again.

We had an excellent trip with Finnair. This was our first time and we’re very pleased. The only issue was with the boarding - it was a little bit confusing and needs a little bit of streamlining.

Crew very lovely. Arrived an hour late due to bad weather. We were given new tickets to an other flight but it could have been organised better, so we did not have to run through the whole airport to.

Flight delayed over an hour. They said they would hold our connection but then did not.

Food can be better. Taste and option, the pasta wasn't the greatest.

Horrible flight cancelled had to buy another very expensive ticket

W ended up getting stuck in Edinburgh Scotland during the air strike. They cancelled our flight and No help to get us rebooked. All said down that cost us over $2,000 extra at least to get home. Hopefully we will be reimbursed somehow! Won’t be flying Air Canada again

The flight attendants were not very nice. No smiles On my return trip I was charged for one bag $83.30 although I had purchased the flight including one piece of luggage. Can this be refunded to me? Thank you!

Aircanada was not great. Didn't get anything to eat. No snacks. No entertainment. Horrible checking in.

They screwed up so bad, I asked for a short check for my luggage since we had a 21 hour overnight layover in London at a hotel. They said I have to receive my luggage in London because it’s an overnight layover. Get to London, nope, my bags aren’t coming off they are staying in terminal 5 over night and going straight to Ibiza. So we had no luggage for a whole day and basically stuck with no clothes or washroom stuff. Finally get to Ibiza and my luggage is completely smashed and damaged and missing a wheel. Now I have to drag this 50 lbs luggage around Ibiza islands for 10 days. Wtf. So pissed off Air Canada is LITERALLY THE WORST AIRLINE IN THE WORLD

This was an excellent experience for a very short flight.

Easy boarding and comfortable seating were plusses. Enjoyed the experience and good service from the captain and crew. Many thanks...!

I rarely fly but the boarding was very good, seats are ok, it's economy right ? The food was alright, nothing to write home about, the flight attendants were awesome. The flight was uneventful, a little turbulence, take off and landing were good. For someone who doesn't fly that much I'd say it was pretty good overall.

The experience with air Canada, was not really good, first they try to charge for the seat again in the counter after being paid in advance, second we have to wait for a hora inside the plane before departure for mechanics problems

Very bad. Business class money is paid but service is worst than economy with empty middle seat. Very low grade food, very poor toilet. This should be highlighted as worst business class in the world. Government of Jordan should ban British airways for misleading information.

Decrepit planes, poor business class layout designed to maximize revenue, no decent movie selection.

It was great. Enough space and room for legs . Great service to.

I was attacked in the Miami airport and the staff did nothing. On my flight from London to Miami one of the flight attendants screamed at me and demanded I keep my seat in the upright position at all times during the fight so the man behind me was comfortable for the flight. I will never in my life use British airways again

I had great difficulty in switching flights. The airline said it was up to Kayak and Kayak said it was up to the airline! Incredibly frustrating!!!

Excellent everywhere but Philly, the most rotten airport in the world.

Fair, difficult to find the departure gate. Luggage delayed on arrival

Not so good with their baggage handling as they damaged one of my check in luggage

Plane is old. Toilet did not work. Once in Singapore the continuation to London was cancelled.

Easy boarding, very friendly crew, short flight so no entertainment… needed cc for all food and drink purchases…. clean and on time … that is all that mattered… so overall very good.
